Each inclusion uses regular expression pattern matching, and must be separated by a new line.
This is useful when you need to check out an entire resource for building, but only want to do the build when a subset has changed.
/trunk/myapp/c/library1/.*
/trunk/myapp/c/library2/.*
If /trunk/myapp is checked out, the build will only occur when there are changes to either the c/library1 and c/library2 subtrees.
